cycle 0097 tidy (clean). Architect drift review over 485f3c8..HEAD: no code
drift, no debt. Regression: no dedicated script (architect is the sole gate);
its "What holds" is non-empty (design commitments confirmed against the diff):
- Inv. 8 / 9: the cycle touches only crates/aura-cli (main.rs + cli_run.rs +
the ephemeral spec/plan); walk_forward/WindowRoller/FamilyKind::WalkForward/
append_family/put_blueprint are read-only reuse, no engine/registry change.
- Inv. 1 / 2: blueprint_walkforward_family reuses the generic walk_forward roller
(windows disjoint-parallel, across-sim); each IS-sweep/OOS-run sees only its
window's windowed_sources; IS precedes OOS per window — no look-ahead.
- Reproduce lockstep: the reproduce_family_in WalkForward arm rebuilds each OOS
slice from stored.manifest.window (before the _ => run_sources fallthrough that
would rebuild the wrong full-window source); winner params via the shared
manifest->cells recovery; pinned by the reproduces_bit_identically E2E.
- Structural mirror + panic-safety: one-substitution-deep twin of the hard-wired
Stage1R arm (select_winner + walk_forward reused, metric sqn_normalized);
run_blueprint_walkforward follows the content-addressed sibling pattern (no
ensure_name_free); blueprint_sweep_over returns Result<_,BindError>, a bad axis
is in-closure exit 2 (never a panic); run_oos_blueprint derives pip internally
(7 args, no #[allow]).
Ledger: refreshed the C24 realization block (docs/design/INDEX.md) — replaced the
now-false "Walk-forward is deferred (#173, dep #169)" sentence with the "IS-refit
walk-forward shipped (cycle 0097)" note; and extended the C18 reproduction note —
reproduce now spans the third family kind (WalkForward), so all three FamilyKind
variants persist AND reproduce through the one shared topology_hash+put_blueprint
hook.
Milestone: the World/C21 blueprint-data family surface (run/sweep/mc/walkforward/
list-axes/reproduce) is coherent and complete per the architect review — no
structural gap. This audit proves drift-clean; a green end-to-end MILESTONE
FIELDTEST remains the deliberate gate to formally close the World/C21 milestone.
Ephemeral spec/plan git-rm'd per the lifecycle convention.
